For fans still searching for a TV show like The Expanse, it’s hard to find one that hits the same mix of complex politics, gritty space travel, and compelling characters - and there’s a show from decades earlier that could be the answer. The critically acclaimed The Expanse wrapped its six-season run in 2022, leaving a vacuum in the genre that few shows have managed to fill. The Expanse took viewers across the solar system and deep into the geopolitical tensions between Earth, Mars, and the Belt, all while introducing powerful alien technology that rewrote the rules of reality. With its mature tone, grounded world-building, and multifaceted characters, The Expanse set a new standard for modern science fiction television.
